Help with Water Tank For Food Trailer

Hello, I am having trouble finding a water tank that fits our needs and thought someone here might have some advice. I am searching for a 28-30 gallon water tank to serve as a waste tank. because we are mounting it underneath the trailer, our dimensions are limited. the tank needs to be no deeper than 10", no wider than 22" and no longer than 40". Any help is greatly appreciated, thank you!

Check out ebay. Search grey water tanks or waste water tanks. I am also mounting mine underneath and I found a place in Adrian Michigan that has a lot of different sizes. I live close to there and was able to pick mine up but they do offer shipping. Good luck!

I don't think they make a 31 gallon tank. LOL But take your measurements and put them into the search engine of your choice and see what comes up. Or search the gallon range you mentioned. And last but not least change the size of your fresh water tank slightly so that the % will work with your local HD rules. That's what most builders end up doing.

It seems that a lot of folks are mounting these HDPE tanks under their trucks/trailers to use as greywater tanks. Are you guys covering your tanks with some sort of protective barrier? I recently mounted my tank, and it seems pretty thin and flimsy, like it could spring a leak if a large-enough rock gets kicked up. I am referring to a tank such as this: pplmotorhomes.com/parts/rv-pumps-water/rv-water-tanks-groupphoto.jpg

I second the motion on plastic-mart.com tanks. My 50-gal gray water tank came loose (it's embarrassing) and got dragged under the stepvan, pushed along by the rear wheels, for at least a few hundred yards while I was thinking "what is that peculiar noise". It did tear up the threaded fitting where the drain is, and there are some hairy looking gouges, but I re-mounted it (with angle iron and threaded rods this time) and it doesn't leak.

Polyethylene is extremely hard to fracture, a rock will not hurt it and will probably not even leave a mark.

[Edit: yeah, according to the respective sites the PPL Motorhomes tanks are 1/8" HDPE while the Plastic Mart ones are 1/4" to 3/8". --KH]

TamaleTrolley,

Hahaha, wow...I'm sorry for laughing but that was certainly a good (if unplanned) durability test for your tank! Thanks for the input; I am starting to second-guess my sheet-aluminum shroud I was in the process of fabricating :)

It depends on how long you intend to go without dumping/filling and how much gray water you expect to produce I suppose, but in conventional food truck circumstances I think that is absurd. I have 40 gallon fresh tank and 50 gallon gray and I have the biggest tanks in my whole area. I have never even heard of a food truck with a gray water tank larger than 50 gallons.

With 80 gallons of fresh + miscellaneous crap you are going to be pouring into the sink you will hauling about 700 lbs of water around! It could be you really need it but you would need to know that, not be talked into it by some builder, it is not normal capacity at all.
